Train Traffic Ahead

Something I struggle with pretty regularly are the negative feelings of hostility, frustration, and annoyance when stuck on the subway. There feels like such a loss of control to have my time be at the whim of the MTA on a daily basis. 

I find myself asking the question, "Even considering a train delay, do I arrive late to where I'm going, or am I on time?" It seems that the train often "feels" like it's flying and making great time, and sometimes it's constantly dragging, and "feels" like I must be over 30 minutes behind schedule. Am I? Are these feelings accurate? Are the connected thoughts really facts?

No matter how the ride "feels," can I be with that feeling before it mutates into something negative?
